The speed sensor is an inductive proximity sensor that detects metal parts from a distance of 0.4 mm. This sensor is usually mounted to the sprayer frame or axle from the inside of the wheel. The sensor must be placed in the axis with the bolts (studs) and during hub rotation the gap between the sensor and the bolts should be between 1 mm and 2 mm. Correct sensor operations is indicated by the LED located in the sensor flashing during hub rotation. Every time the bolt approaches the sensor, the sensor LED should flash.
